Application filed April 8,

My invention relates to film packages and.

has for its primary object the provision of means for facilitating thecoiling of a strip of film within a box or casing.

More specifically, it is an object of this invention to provide withinthe film box a spring guide for a strip of film; which guide is providedwith a coating which substanti ally reduces the friction of the filmagainst the guide during the coiling operation.

Other'objects and advantages in details of construction and operationwill be apparent as the description proceeds, reference being had to thefigures of the accompanying drawing wherein like reference numeralsindicate like parts.

Figure 1 is a perspective View of my film package utilizing-myinvention.

Figure 2 is a detail cross sectional view of such a package.

Figure 3 is a detail improved film guide. Figure 4 is an enlargedendview thereof. The reference numeral 1 refers to ahol 2 low box orcasing within which is adapted to be coiled a strip of film 2, the, freeend 3 perspective view of my of which extends'through an opening 4:.at--

one corner of the box, said opening being provided on one side as at 5with a strip of velvet 'or other suitable material for reducing thelikelihood of scratching the film and for preventing the entrance oflight through the opening 4 into the box.

The box 1 ishollow as at 6 to provide a i chamber for the film 2 andprojecting into this hollowchamber 6 is a spring film guide, the innerportion of which comprises the substantially circular spring fingers 7within which the film 2 coils. I

The outer end of the film guide comprises a flat piece of materialpreferably integral with the fingers 7 bent upon'itself as at '8, theupper flange or flap 9 of which extends over the top a mental to thesensitive film,

10' of the casing adjacent its frontedge, and the lower flap or flange11 lying within the opening 4 and carrying a strip of velvet or othersuitable material 12 directly opposite the similar strip 5 on the boxitself. It is be-. tween these two strips of velvet that the film iswithdrawn or inserted with respect to the End pieces 9* are providedateither end of the box 1 to exclude the light therefrom and these endpieces are provided at one corher with flanged ears 9 which serve thetwofold purpose of reventing light from entering the ends 0 the opening4 and of securing the upper flange 9 of the film guide to the box.

The spring finger guides 7 are provided on their inner surface with acoatin 13 of wax or other suitable material which 1s not detrifor thepurpose of reducingthe friction of the film against such guides as thefilm is coiled up therein. By thus reducing the friction between thefilm and the spring fingers 7, with this wax coating, 1 not only greatlyfacilitate the coiling of lessen to a marked degree-the likelihood ofthe film within the box but.

scratching the film through contact with the metal guides 7.

I do not limit myself to the use of wax as a coating as obviousl anysubstance which will accomplish the a ove described purpose withoutinjury to the film, will sufice. I do not limit-myself, therefore, tothe exact form herein shown and described the appended claim.
